20140260250 | APPARATUS, SYSTEMS, AND METHODS FOR LOW GRADE WASTE HEAT MANAGEMENT - The present invention relates to apparatus, systems, and methods of managing large quantities of low-grade waste heat energy by 1) generating excess electric power via an ORC process driven by the removal and recovery of waste heat under favorable operating conditions, and 2) utilizing the same apparatus to provide waste heat removal via a refrigeration process that consumes electric power when environmental conditions do not permit operation in the ORC mode. The mode of operation of the system is principally determined by the thermal energy of the waste heat stream and the availability, or lack thereof, of adequate cooling resources. Such resources are often subject to local environmental conditions, particularly ambient temperature which varies on a diurnal and annual basis. | 09-18-2014 |
20140033711 | MULTIPLE ORGANIC RANKINE CYCLE SYSTEM AND METHOD - Systems and methods are provided for the use of systems that recover mechanical power from waste heat energy using multiple working expanders with a common working fluid. The system accepts waste heat energy at different temperatures and utilizes a single closed-loop circuit of organic refrigerant flowing through all expanders in the system where the distribution of heat energy to each of the expanders allocated to permit utilization of up to all available heat energy. In some embodiments, the system maximizes the output of the waste heat energy recovery process. The expanders can be operatively coupled to one or more generators that convert the mechanical energy of the expansion process into electrical energy. | 02-06-2014 |
